On Thursday I will begin a long journey to open source every household appliance. I am beginning with a refrigerator, because it is the most costly home appliance (aside from washer/dryer). My half-fridge sized prototype is available now:http://grabcad.com/library/the-peltier-fridge

Its simply not possible to make an efficient fridge with peltier coolers.Their efficiency is far too low , typical Carnot efficiency for a peltier cooler is 5%compared to around 50% with a compressor fridge.

Its simply not possible to make an efficient fridge with peltier coolers.

I'm not sure about efficiency but If its possible to make ice its definitely conceivable to make an off-grid/portable solar powered fridge that wouldn't be possible with compressors. This is something that I have ideas about. If you make the project completely open source I'm in. I would really like to see if the efficiency of a peltier cooler really gets in the way of making this a reality.
